SIDEHWALK-LIGHT.

Specification of Letters Patent.

Patented April 3, 1906.

To (all whom it may concern: I

Be it known that we, CHRISTIAN H. Ross and SAMUEL DAUOHY, citizens ofthe United States, residing in Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inSidewalk-Lights, of which the following is a specification.

Our invention relates to sidewalk-lights, and has for its object toproduce an improved construction of this kind.

It consists in the details set forth in the accompanying specificationand described in the claim. I

In the accompanying drawings, Figure 1 is a perspective view of themetallic ring surrounding the lens; Fig. 2, a perspective view of thelens, and Fig. 3 a sectional view of one of the lenses in position.

As shown in the drawings, a is an iron frame or plate provided atintervals with openings 6. These openings at the lower surface of theplate a are provided with beveled sides h. On the upper surface of theplate the openings are rabbeted, so as to form seats is for the lens. Asshown, the lens comprises an enlarged lower portion 0 and an upperportion 0 integral therewith, slightly inclined circumferentially. Ashoulder surrounds the lens at the point 0 between the upper and lowerportions. The lower portion of the lens is provided with spaced ribs f,as shown, and the upper portion is surrounded by a flanged ring g, oflead or similar material. The horizontal flange g of the rings restsupon the shoulder 0 and the vertical side of the ring is inclined, so asto fit the inclined circumference of the lens. The lenses, having theirrings in position, are seated in the seats 7c, and a layer of cement,concrete, or other like material is placed upon the iron frame or plate,filling in all the space between the lenses, the upper surface of theconcrete layer being in the same plane as the upper surface of thelenses. It will be understood that the supporting-plate is provided withas many openings and lenses as desired, though we have illustrated butone in the drawings.

It will be seen that the lenses are securely held in their seats by thelayer of cement which lies over the shoulders of the block and theflanges of the lead ring and fills the spaces between the verticalflanges. The ring is also by this means held securely in place andprevented from vertical movement, so that it is impossible for one ringto be forced out of place and broken off. Thus it will always serve toprotect the edges of the glass or translucent material of the lens. Theinclination of the sides of the upper portion of the lens and of thesurrounding ring also serves to hold the parts firmly in place bycausing them to wedge firmly together.

We are aware that prior to our invention many forms of lenses have beenused; but we are not aware that a lens having the retaining means shownin our present application has ever before been proposed.

Ive claim In a sidewalk-light, the combination of a supporting-platehaving rabbeted openings, lenses mounted in the rabbeted openings, saidlenses comprising a circumferentiallyinclined upper portion, an enlargedlower portion having spaced ribs, a shoulder between the upper and lowerportions, a metallic ring surrounding the upper portion having a flangearound its lower edge adapted to rest on the shoulder, and a filling ofplastic material between the ribs.
